These 3-ton cargo trucks became the back bone of the German military transports. The military designation for these 3-ton trucks was Kfz. 305. Originally designed as a 4X2rear-wheel drive but in 1940 a 4-wheel design was made available and it became very much appreciated by its crew for the cross country abilities. This variant of the 3-ton was used primarily for cargo transportation but could easily be adapted to handle troops. These 3-ton trucks continued to be manufactured even when WWII was declared ended and the S type became the most used truck for German commercial transport. From1937 to 1944 approximately 82,000 of the Type were built and another 14,000 with along wheel-base and 8,300 with a low-level base.

In 1939 Germany had developed a 2 cm Flak 38 gun that was an improvement over the previous Flak 30. The 38 had almost double the rate of fire and the weight had been reduced. The Flak 38 became the primary light weight anti-aircraft gun and was towed or mounted on just about ever kind of German vehicle during WWII. One vehicle that had the gun mounted on it was the old reliable 3-ton truck whose 2 side and 1 rear panels were hinged at the bottom and would be lowered opened.
